drm/amd: kill the outdated "Only the pthreads threading model is supported" checks
Nowadays task->group_leader->mm != task->mm is only possible if a) task is
not a group leader and b) task->group_leader->mm == NULL because
task->group_leader has already exited using sys_exit().
I don't think that drm/amd tries to detect/nack this case.
